With the Indigo Lanterns released from their connection to the Indigo Light, the most dangerous people in the universe are free and angry. This includes Black Hand, the former general of Nekron, who has been their prisoner since the end of Blackest Night.

Hand does what you’d expect from someone desperate to be free from the control of power ring, and dives off a cliff, crashing into the rocks below and dieing on the spot.
